WINDOW FOR AUTOMOBILES.

Application filed January 13, 1919. .Serial No. 270,826.

T 0 all whom it may concern:

7 Be it known that I, HORACE T. THOMAs, a citizen of-the United States,residin at Lansing, county of Ingham, State of Michigan, have invented acertain new and useful Improvement in lVindows for Automobiles, anddeclare the following to be a full, clear, and exact description of thesame,- such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to windows for automobile curtains and an object ofmy improvements is to provide a structure which shall permit of theready adjustment and removal of the window pane without preventing therolling up of the curtain and provide a cheap and eificientconstruction.

I secure this object in the device illustrated in the accompanyingdrawings in which:

Figure 1 represents the rear curtain of an automobile provided withapparatus embodying my invention.

Fig. 2 is a detail showing a part of a cur tain to illustrate the methodof construction.

Fig. 3 is a horizontal section of a window and adjacent part of thecurtain.

Fig. 4 is a vertical section of the same to an enlarged scale. I

Fig. 5 is a perspective view of the window pane removed from theremainder of the construction.

Figs. 6, 7 and 8 are perspective views of modified forms of the windowpane.

Fig. 9 is a detail cross section of the intermediate strengthening partin Fig. 8.

a is the curtain, Z) the openings or the windows in said curtain. 7indicates the window pane. The edges of the openings 12 are strengthenedby the construction illustrated in Fig. 2 which shows a rectangularopening cut through the curtain of somewhat smaller dimension than theintended opening for the window. The material is then cut in at thecorners as indicated by the reference character 6 and the flaps b areturned over as represented at the right of Fig. 2 and are sewed to themain portion of the curtain. A rectangular piece 6 which may be of thesame material of the curtain is then provided turned over as indicatedto forma double thickness and shaped to the size and contour at itsinner edge of the completed window opening. The piece 6 is then placedover the flaps b and sewed thereto and to the main portion of thecurtaln a by stitches along the sides and bottom. The upper portion ofthe frame piece 6 being left free as indicated at (Z Fig. a so thatthere shall be a mouth or opening at this point to permit of theintroduction of the window pane. The line of stitching e is at somedistance from the edge of the opening so as to leave a pocket orretaining guide a at the sides and bottom of the openlng to secure thewindow pane accurately in place.

1 form the window pane of transparent sheet material which may becelluloid and of a shape to cover the opening and extend somewhat beyondthe edges thereof so as to engage in the guides or pockets e I providethe window panes f with transversely extending stifi'ening pieces whichmay be pieces of sheet metal i as shown in Fig. 5

extending across the upper and lower edges and this sheet metal may bepunched or indented at f to firmly secure the strip in place, or thematerial itself may be turned over at the upper and lower edges asindicated in Fig. 6, or the material at the upper and lower edges may beturned over and have a metal rod 7" inserted through it, as shown inFig. 7. \Vhile I regard it as preferable to have the transverselyextending stiffening parts at the upper and lower edges because thatthen, if of opaque material, they do not obstruct the view through thewindow, but a transverse stiiiening piece may be used intermediate theends, as shown at f in Fig. 8, where the ends of the metal strip f areturned over and clamped upon the edges of the window pane. This strip imay be of thin material and formed in cross section, as shown in Fig. 9,to se cure stiffness and strength.

A window pane constructed as above de scribed is inserted through theopening (i and engages in the pockets or guides between the frame strip6 and the over-turned portions 6 of the window curtain. These willremain fixed in place and the curtain may berolled up, the window panebeing rolled with it in the usual way. The window pane may be easilywithdrawn and replaced so that it may be cleaned or a new panesubstituted and the pane is cheap to construct and the curtain isreadily adapted to receive the construction as shown.

What I claim is:

1. The top curtain for vehicles having a window opening therein, guidesat the sides of said opening adapted to slidably receive and retain awindow pane, a flexible transparent window pane adapted to cover saidopening and have its side edges slidably engage in said guides, saidpane being provided with a narrow stiffening part extending transverselythereof and rigidly secured thereto, the ends of said stiiiening partslidably engaging in said guides so as to prevent the displacement ofsaid pane in a direction at right angles to the plane of said opening.

I 2. The top curtain for vehicles having a Window opening therein,guides at the sides of said opening adapted to slidably receive andretain a window pane, a flexible transparent window pane adapted tocover said opening and have its side edges slidably engage in saidguides, said pane being provided with a narrow stiffening part at itsupper and lower edge extending transversely thereof and rigidly securedthereto, the ends of said stiffening part slidably engaging in saidguides so as to prevent the displacement of said pane in a direction atright angles to the plane of said opening.

In testimony whereof, I sign this specification.
